Make setting under PID control
To enable PID control, you need to set function code J01 to 1 or 2.
Under the PID control, the items that can be set or checked with the
and keys are different
from those under regular frequency control, depending upon the current LED monitor setting. If the
LED monitor is set to the speed monitor (E43 = 0), you may access manual feed commands (Ref-
erence frequency) with the
and keys; if it is set to any other, you may access PID process
command with those keys.
Refer to the FRENIC-Mini User's Manual (MEH446), Chapter 4, Section 4.8 "PID Frequency
Command Generator" for details on the PID control.
Setting the PID process command with the built-in potentiometer
(1) Set function code E60 to "3: PID process command 1."
(2) Set function code J02 to "1: PID process command 1."
Setting the PID process command with the
and keys
(1) Set function code J02 to "0:
/ keys on the built-in keypad."
(2) Set the LED monitor to something other than the speed monitor (E43 = 0) in Running mode.
This setting is possible only in Running mode.
(3) Press the
or key to display the PID process command. The lowest digit of the displayed
command and the decimal point blink.
(4) To change the PID process command, press the
or key again. The PID process com-
mand you have specified will be automatically saved into the inverter’s memory. It is kept there
even if you temporarily switch to another means of specifying the PID process command and
then go back to the means of specifying the PID process command via the remote keypad. Also,
it is kept there even while the inverter is powered off, and will be used as the initial PID process
command next time the inverter is powered on.
• Even if multi-frequency is selected as the PID process command (SS4 = ON), you still
can set the process command using the remote keypad.
• When function code J02 data has been set to any value except 0, pressing the
or
key displays the PID process command currently selected (you cannot change the set-
ting).
• When a PID process command is displayed, the decimal point next to the lowest digit on
the LED display blinks to distinguish it from the regular frequency setting. When a PID
feedback amount is displayed, the decimal point next to the lowest digit on the LED
display is lit.
